The genus Raoultella is composed of Gram-negative, oxidase-negative, aerobic, nonmotile, capsulated, facultatively anaerobic rods (formerly designated Klebsiella) in the family Enterobacteriaceae. It is named after the French bacteriologist Didier Raoult.

Members of genus Raoultella grow at 10 °C consistent with their recovery from plants, soil, and water, whereas members of Klebsiella ( is an exception, and a proposal to classify K. oxytoca in a separate, unnamed genus has been made). do not grow at 10 °C and are mainly recovered from mammals' mucosae.

It consists of species Raoultella electrica, , Raoultella planticola and Raoultella terrigena.

A phylogenetic tree of Klebsiella, based on a 2.93-Mbp alignment, unambiguously places R. ornithinolytica sister to K. oxytoca within the larger Klebsiella phylogeny and suggests abandoning the Raoultella genus designation.
